Eve no Okusuri is a really nauty manga. This is not for the fans of "fluffy yuri", there's a ton of lesbian sex involving underage girls with older women (there's even some bondage play). If this is not for you just stay away.
But you are a little devil aren't you? It's ok :)
Overall, it was an entertaining story with some really hot sex scenes. I found the ending a little lacking, emotionally. Other than that, I'd say this manga is pretty good for what it's going for. Recommended for mature yuri fans.
